2022-02-23: Are Cosmic Strings Cracks in the Universe?

  • 04:51: ... pulling them towards the same value, just   like how the magnetic dipoles in a ferromagnet  drag each other into alignment. So, when ...

2021-07-07: Electrons DO NOT Spin

  • 07:02: ... the direction  of a rotation axis, or the north-south pole of the magnetic dipole. ...

2021-04-07: Why the Muon g-2 Results Are So Exciting!

  • 01:18: And that's the anomalous magnetic dipole moment of the muon.
  • 01:35: What's an anomalous magnetic dipole moment?
  • 01:41: We've actually talked at about the anomalous magnetic dipole moment before in terms of the electron.
  • 06:34: By the way, the anomalous in the anomalous magnetic dipole moment, refers to that little bit extra after the two.
  • 09:49: The muons interact with the magnetic field and their own magnetic dipole axis, rotate like a top just before it falls.

2020-11-04: Electroweak Theory and the Origin of the Fundamental Forces

  • 09:35: Consider a magnetic material, made up of many little magnetic dipoles, like little bar magnets that can point in different directions.

2019-09-16: Could We Terraform Mars?

  • 18:38: ... a south magnetic pole - as in, what we would call the south pole of a magnetic dipole or a bar ...

2018-08-15: Quantum Theory's Most Incredible Prediction

  • 01:53: ... measuring the G factor, or in simple English, measuring the anomalous magnetic dipole moment of the ...
  • 02:10: What is the anomalous magnetic dipole moment?
  • 02:14: Well, it's just like the regular magnetic dipole moment but more anomalous.
  • 02:21: Let's break down these magnetic dipole moment thing.
  • 02:42: The tendency of a dipole magnet to rotate in an external magnetic field is its magnetic dipole moment.
  • 02:50: ... with a dipole magnetic field has a magnetic dipole moment is basically a measure of how much it would interact with an ...
  • 04:20: So electrons have a magnetic dipole moment, meaning they feel magnetic fields and act as little bar magnets.
  • 05:09: ... fact, weirdly, if you measure the magnetic dipole moment of an electron, you get almost exactly twice the value you'd ...
  • 07:02: And this is the anomalous magnetic dipole moment.
  • 09:04: ... interaction with the magnetic field when we calculate the electrons magnetic dipole moment and it's G ...
